The present invention relates generally to phonograph turntables and, more particularly, to slip mats used with a phonograph turntable.
Phonograph slip mats are known in the art and are essentially circular pieces of slippery cloth or synthetic material that are designed to allow disc jockeys (DJs) to manipulate a vinyl phonograph record on a phonograph turntable independently of the platter. The slip mat is positioned directly between the record and the deck platter. The slip mat reduces friction, allowing the platter to continue to turn underneath the record. When in operation, the user can hold a record in a fixed postion for “slip-cueing.” When slip-cueing at the moment the user wishes to start playing the record, the turntable continues to rotate underneath the record. Thus, the record does not need to rotate up to speed as it has always been rotating underneath the record. Slip-cueing is used by DJs for beatmatching when trying to start a record with the bass beats playing simultaneously with another record. Secondly, “back spinning” is used by DJs who pull a record back and forth to make a scratching sound on the record. A back spin involves spinning the record to retard, arrest, or reverse the linear motion of the record. Slip mats used in the prior art often prevent the platter from being pulled both in forward and reverse direction. This creates too much weight and inertia to back spin the record in a proper manner which can create undesired distortion.
The accompanying figures, where like reference numerals refer to identical or functionally similar elements throughout the separate views and which together with the detailed description below are incorporated in and form part of the specification, serve to further illustrate various embodiments and to explain various principles and advantages all in accordance with the present invention.
Skilled artisans will appreciate that elements in the figures are illustrated for simplicity and clarity and have not necessarily been drawn to scale. For example, the dimensions of some of the elements in the figures may be exaggerated relative to other elements to help to improve understanding of embodiments of the present invention.
Before describing in detail embodiments that are in accordance with the present invention, it should be observed that the embodiments reside primarily in combinations of method steps and apparatus components related to the elevated turntable slip mat. Accordingly, the apparatus components and method steps have been represented where appropriate by conventional symbols in the drawings, showing only those specific details that are pertinent to understanding the embodiments of the present invention so as not to obscure the disclosure with details that will be readily apparent to those of ordinary skill in the art having the benefit of the description herein.
In this document, relational terms such as first and second, top and bottom, and the like may be used solely to distinguish one entity or action from another entity or action without necessarily requiring or implying any actual such relationship or order between such entities or actions. The terms “comprises,” “comprising,” or any other variation thereof, are intended to cover a non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements does not include only those elements but may include other elements not expressly listed or inherent to such process, method, article, or apparatus. An element preceded by “comprises . . . a” does not, without more constraints, preclude the existence of additional identical elements in the process, method, article, or apparatus that comprises the element.
In operation, a first flat washer 205 is positioned over the record centering peg 209 onto the platter 204. Next, the slip mat 200 is positioned over the centering peg 209 and then a second flat washer 207 is positioned over the centering peg 209 on the slip mat 200. A friction clamp such as one or more split lock washers 211, 212 are then positioned on the centering peg 209 over the second flat washer 207 to hold the low-friction turntable slip mat assembly in place. As will be evident to those skilled in the art, the slip mat 200 enables a DJ to have precise control over a phonograph record when slip-cueing and/or back spinning the record. Since the recessed section 203 provides less friction and resistance when in contact with the turntable platter 204, the invention provides superior performance when compared with conventional slip mats used in the prior art.
In the foregoing specification, specific embodiments of the present invention have been described. However, one of ordinary skill in the art appreciates that various modifications and changes can be made without departing from the scope of the present invention as set forth in the claims below. Accordingly, the specification and figures are to be regarded in an illustrative rather than a restrictive sense, and all such modifications are intended to be included within the scope of present invention. The benefits, advantages, solutions to problems, and any element(s) that may cause any benefit, advantage, or solution to occur or become more pronounced are not to be construed as a critical, required, or essential features or elements of any or all the claims. The invention is defined solely by the appended claims including any amendments made during the pendency of this application and all equivalents of those claims as issued.
